Some progress has been-made in the arrangement of the Hxhi- 
bition Rooms. The Indian, the African, and the Australian faunal 
collections are now accessible to the public, although they yet are 
far from complete. The Systematic Collection of Birds has under- 
gone a final arrangement, and the storage rooms devoted to the 
Radiates, the collections of fish and reptile skeletons, and the 
Crustacea, are now filled with their respective collections. 
Mr. Garman has continued the explorations made by him in pre- 
vious years in the West, and he and his assistants have sent us 
valuable additions to our collections of Mammalian and Reptilian 
fossil remains. We have specially to thank the Secretary of War, 
the Hon. R. T. Lincoln, and the Secretary of the Interior, the 
Hon. H. M. Teller, for the letters of introduction they kindly sent 
for the use of Mr. Garman while in the Territories.
